<h2>a. Answer:</h2>
For this question we'll use the following method:
1. Let's subtract old value from new value
185$-160$ = -25$
The negative value implies that the price has decreased
2. Divide the result by the old value
25$/185$ = 0,1351
3. Convert this value to percentage:
0,1351 x 100 = 13,51%
Finally, by rounding to the nearest tenth:
13,5%
That means 13,5% decrease
<h2 /><h2>b. Answer:</h2>
1. Let's subtract old value from new value
77$-56$ = 21$
The positive value implies that the price has increased
2. Divide the result by the old value
21$/77$ = 0,2727
3. Convert this value to percentage:
0,2727 x 100 = 27,3%
Finally, by rounding to the nearest tenth:
27,3%
That means 27,3% increase
Answer:
The Answer is: Lower Level seats = 150. Upper level seats = 200.
Step-by-step explanation:
Start with two known equations:
1 - the number of Lower Level times 35 + the number of Upper level times 25 = the total dollar amount of $10,250.
35L + 25u = 10250
The number of both types of tickets = 350
L + u = 350
Solve for u:
u = 350 - L
Substitute and solve for L, Lower level seats:
35L + 25(350 - L) = 10250
35L + 8750 - 25L = 10250
10L + 8750 = 10250
10L = 1500
L = 150
There are 150 Lower Level seats.
u = 350 - L
Subtract to get the number of upper level seats:
u = 200
Proof:
35(150) + 25(200) =
$5,250 + $5,000 = $10,250
